COMPARING METER AND
LABORATORY RESULTS
OneTouch
®
Ultra
®
Meter test results and laboratory test results
are both expressed in plasma-equivalent units. However, your
meter result may differ somewhat from your laboratory result due
to normal variation. Meter results can be affected by factors and
conditions that do not affect laboratory results in the same way.
Your OneTouch

Ultra

Meter glucose value should agree with a
laboratory measurement within ±20% most of the time under
normal conditions. A result within that range is considered
accurate when testing with the OneTouch
®
Ultra
®
Meter. However,
results can differ by more than ±20% in some situations. See the
OneTouch
®
Ultra
®
Test Strip package insert for typical accuracy
and precision data and for important information on Limitations
of Procedure.
To make an accurate comparison between meter and laboratory
results, follow these guidelines:
Before you go to the lab:
• Perform a control solution test to make sure the meter is
working properly.
• It is best to fast for at least eight hours before doing
comparison tests.
• Take your meter with you to the lab.
